Honorific term used to refer respectfully to the thoughts, intentions, or will of a superior or someone of higher status. Formal and somewhat old-fashioned; in modern Japanese, expressions like お考え or ご意向 are more common.
I would like to ask for the president's esteemed opinion.
Regarding this matter, I would like to seek your esteemed guidance, Sensei.
Compound of 尊 (そん, 'honorable') and 慮 (りょ, 'thought, consideration'). The exact historical derivation is uncertain, but the spelling is conventionally associated with respectful reference to another's will.
